Front wheel drive cars, rule of thumb give less worn tyre in front. Change 4 (or 5 - remember the spare tyre is an exact tyre spare not some small little wheel), can try other brand and experience the difference - which I think is subjective in terms of what is good for (wallet/drive experience/cabin ambient - wear earplugs)
Change just 2 - can also but if want to try other brands then mix brand tyres. Front Michellin / Goodyear, back Contis
I just got quote from nearby tyre shops;
Goodyear Eagle F1 A2 - RM550/pcs - shop owner claims direct Germany import not local manufacture.
Goodyear Eagle F1 D5 - RM485/pcs (this tyre cannot side cross switch during 8K - 10K alignment/balancing services)
Michellin PS3 RM580/pcs
Continental CSC 5 (not MC5) - RM820/pcs
Choices Choices Choices.
Goodyear shop fella added, "Better change now lor - afterwards GST add 6%". Nia-sing! after many nag from accountant go tyre shops also get this acronym.
